ABSTRACT:
The invention provides a brushite coating that is easily convertible to hydroxyapatite at mild conditions. The brushite coating is rapidly electrodeposited from an aqueous electrolyte solution of calcium phosphate, monobasic and salts having cations of ammonium, alkali metals and alkaline earth metals. About 1 to 5 percent of the calcium ions in the brushite coating are substituted with ammonium, alkali metals or alkaline earth metal cations. Hydroxyapatite can be formed by immersing the brushite coating in an animal or human body fluid or a simulated body fluid at from about 20 to 37.degree. C. Substantially stoichiometric calcium hydroxyapatite is formed.
